Polyamines 53-63 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 156-161 9316423-8 1997 Furthermore, direct administration of spermidine to isolated nuclei from polyamine-deficient (caused by DFMO) cells resulted in a 2- to 2.5-fold increase in c-myc and c-jun transcription. Polyamines 73-82 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 157-162 9316423-10 1997 These results indicate that 1) polyamines are required for the transcription of the protooncogenes c-myc and c-jun in IEC-6 cells and 2) depletion of intracellular polyamines has no effect on posttranscriptional regulation of c-myc and c-jun mRNAs. Polyamines 31-41 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 99-104 8572176-0 1995 Gastrin stimulates expression of protooncogene c-myc through a process involving polyamines in IEC-6 cells. Polyamines 81-91 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 47-52 8572176-9 1995 These results show that 1) gastrin stimulates both polyamine biosynthesis and the expression of the c-myc protooncogene, and 2) depletion of intracellular polyamines by DFMO significantly prevented the increased expression of c-myc by gastrin. Polyamines 51-60 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 226-231 8572176-9 1995 These results show that 1) gastrin stimulates both polyamine biosynthesis and the expression of the c-myc protooncogene, and 2) depletion of intracellular polyamines by DFMO significantly prevented the increased expression of c-myc by gastrin. Polyamines 155-165 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 100-105 8572176-9 1995 These results show that 1) gastrin stimulates both polyamine biosynthesis and the expression of the c-myc protooncogene, and 2) depletion of intracellular polyamines by DFMO significantly prevented the increased expression of c-myc by gastrin. Polyamines 155-165 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 226-231 8048943-2 1994 Elevation of cellular polyamine content triggered the transcription of c-myc and c-fos. Polyamines 22-31 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 71-76 8203532-1 1994 The current study determines the hypothesis that expression of protooncogenes c-fos and c-myc is involved in the mechanism of polyamine-stimulated healing in gastric mucosal stress ulcers. Polyamines 126-135 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 88-93 8368314-2 1993 This study tests the hypothesis that the protooncogenes c-fos, c-myc, c-jun, and junB are involved in the mechanism by which polyamines modulate mucosal growth. Polyamines 125-135 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 63-68 19812253-3 2009 Here, we show that in rat intestinal epithelial cells (IECs), polyamines enhanced HuR association with the 3"-untranslated region of the c-Myc mRNA by increasing HuR phosphorylation by Chk2, in turn promoting c-Myc translation. Polyamines 62-72 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 137-142 19812253-3 2009 Here, we show that in rat intestinal epithelial cells (IECs), polyamines enhanced HuR association with the 3"-untranslated region of the c-Myc mRNA by increasing HuR phosphorylation by Chk2, in turn promoting c-Myc translation. Polyamines 62-72 MYC proto-oncogene, bHLH transcription factor Rattus norvegicus 209-214
